I believe they are, but man the audio quality is not on par with most late 80's sbd's. All of these 87 shows labeled "This is a pretty hissy matrix sbd with lots of audience" by Charlie in the notes at the bottom of the page are spot on. My take is to pass on them as there are plenty of fine straight up aud sources to listen to that have far better dynamics than these latest ups. A lot of solid rigs/tapers in the late 80's captured the dead in the audience.

like I said in another review, no offense to you or your work Charlie. I don't think much could have helped source material of this quality. The only thing that sparks my curiosity is where these sources came from and what was Healy thinking recording a sbd/matrix of this quality night after night in the spring of 87?
